7 Nov 29, 2005 JMS - Primary features The primary features of JMS are as follows: Connection Factories are used in JMS to create connections to a specific JMS provider. In JMS, both Publish-Subscribe Messaging and Point-To-Point are implemented and defined by separate interfaces so that a Provider does not have to support both. JMS defines the concept of a Topic or a Queue as the target for a Message. Topics are used for Publish-Subscribe Messaging. Queues are used for Point-to-Point Messaging. The Providers’ code is defined by interfaces in JMS, freeing the implementation from the limitations of subclassing. JMS provides support for distributed transactions.
